In this paper, the dynamic behavior of axial (AX) and transverse coupled vortex-induced
vibration (VIV) of composite riser under gas-liquid two-phase internal flow is studied. Firstly …

Lazy wave risers (LWRs) are designed with equidistant buoyancy blocks attached in the
lower half of the riser, allowing the riser to take on an arch shape under the buoyancy forces …

Abstract Vortex-Induced Vibration (VIV) caused by ocean current is one of the main sources
of the long-term fatigue damage of marine riser. Buoyancy module is an essential equipment …

This paper describes a novel flow control scheme over circular-cylinder wakes using parallel
symmetric jets. The effects of different jet momentum coefficients (C m) at θ=±30° on vortex …

This paper reports the experimental results of the vortex-induced vibration (VIV) of an S-
shaped flexible riser hanged underneath a two-degree-of-freedom (2-DOF) oscillating …

Vortex-induced vibration will occur due to the vortex shedding around the marine towing
cable during the towing movement, which will further affect the acquisition efficiency of the …

DSR (Deep steep riser) is a new riser structure that reduces the ultra-high-tension load
caused by the riser self-weight. In this paper, the mechanical behavior of DSR under …

Coupled equations of the dynamic model and the Van der Pol wake oscillator model are
solved by the central finite difference method for the deepwater drilling riser. The vortex …

Experiments were conducted on risers with different mass ratios to study the effect of mode
conversion and spanwise correlation. The slenderness ratio of the riser model was set as …

In ultra deep-water environments, deep steep riser (DSR) can optimize the ultra-high-
tension loads caused by the weight of the riser. In this paper, the influence of the buoyancy …
